When in very hot weather driving slow air conditioning blows hot air. Any ideas?

(2003 Ford F-250 Super Duty)
Why would my air conditioning not work on a dirt road in very hot weather driving slow?
What seems to make the problem better or worse? Driving slower on a dirt road
How long have you had this problem? Just the last few weeks

Insufficient air flow into engine bay.

IF your primarily travel is under the same conditions that are posted here - then you might want to seek *hands-on* assistance from qualified personnel to formulate a repair solution .... This is especially true if engine overheating is also occurring.

However I suspect the ‘this’ particular problem goes away during ‘normal’ highway travels.

Good luck!

...which would lead me to suggest having a look at your radiator / condenser fan operation.

Still, with low engine speeds, your compressor isn't turning fast enough either. Optimal air conditioning compressor operation occurs somewhere above 1,500 RPM -- if you're crawling along, it might be a bit to slow for optimal performance.
